In those circumstances, you can hire a cheap writer to churn out hundreds of crappy pages based on product data sheets or you can hire a developer to make a template system that does more or less the same thing.
I don’t think content is automatically low quality with automated SEO. And if it is, it won’t work because users won’t find it helpful. The goal, like all good content, is to help people. But I understand if you’re skeptical.
I don't think anyone's suggesting that. After all, most content produced by humans is low quality as well.
Generating good content generally requires someone to be a subject matter expert and to present the issue at hand in sufficient depth. Most content answers questions, but good content answers the right questions.
Looking at your site, I believe the main issue is that so much content is repeated between each individual plant. There's also just not that much content to begin with. A human could have copy-pasted these articles and swapped out the pictures within a few minutes.
The largest issue is Google's crawl budget. With limited domain authority, it will be hard to get xx,xxx+ pages indexed without a meaningful number of quality backlinks. Low MSV queries are even tougher if you don't rank #1, too, so using GSC to A/b test titles/descriptions CTRs will be super helpful. On-site interlinking will also be another easy way to juice visibility.
